Elllldlii forming' part of :Letters atent No. 668,007, dated February12, 19014 Application filed October 30, 1900. Serial No. 34,927. (Nomodel.)

Be it known that l, FERDINAND L. CAPES, a citizen of the United Statesof america, residing at Atlanta7 in the county of Logan and State oflllinois,haveinvented certain new and useful Improvements in Fruit-TreeSprayers or VWagon-Power Tree-Sprayers, of which the 'Following is aspeciticaiion, reference being had therein to the accompanying drawings.

This invention relates to spraying appara lus, and particularly to thatclass designed for spraying Afruit-trees and the like with so lutionst'or destroying insects.

One object ot' the invention is to provide n'ieans for storing pressurewhile the vehicle carrying the solution is in motion, so that the saidsolution may he forced` through the sprajfinghose when the vehicle is atrest. This is especially i'lesirable where the trees diller in size oran unusual ainountof the solution is required alv a single point-as7 forinstance, when a tree or plant is unusually infested with insects-for itenables the operator to stop under such tree and direct the solution tosuch points as will prove most eflteetive.

A further object ol` the invention is to produce a device which will actin conjunction with receptacles, such as barrels, containing thesolution in such manner that the receptacles may be emptied iusuccession.

Furthermore, an object of the invention is to produce novel means ofregulating the stroke of a pumps piston that the pressure in a tank, tobe hereinafter known as the pressu re-tani 1,7 may be limited to anymaximum pressure desired.

Finally, an object of the invention is to produce a spraying apparatuswhich will pos sess advantages in points of simplicity, durability, andefficiency, proving at the same time comparatively inexpensive toproduce and sustain.

lVith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and coinbination ol"parts to be hereinafter more fully set forth and specitcally claimed.

ln describing the invention in detail reference will be had to theaccompanying drawings, forming part o t' this specification, whereinlike characters denote corresponding parts in the several views, and inwhich- Figure 1 is a view in elevation of a vehicle with apparatusembodying the invention applied. Fig. 2 is a longitudinal sectional viewof a portion of a pitman.

In the drawings, 1 denotes avehicle, 2 the wheels thereof, and 3sprocket-wheels taking motion from the wheels 2. A crank-shaft 4 isjournaled in suitable bearings at the rear of the vehicle and carriesthe sprocket-Wheels 5, and the sprocket-chains 6 connect thesprocket-wheels 3 and 5 for drivingthe erankshaft. Stationed on thevehicle is atank 7, having suitable outlet-s 8 at bottoni of tank, towhich the si'naying-hose i) are attached. These outlets 8 are the onlyones provided for the tank, for it is air-tight for the purpose ot`causing the air therein to gain increased pressure as liquid is forcedtherein through the medium of the pump l0. rlhe pump has a cylinder inwhich a piston l' reeiprocates, and the ()iliiicl \,1'lietd 1l has apacking-box l2 for the reception of the piston-rod 13. The branch pipesl-t of the cylinder lead to the tank 7 and are suitably valved to permitthe fluid to flow only from the cylinder to the tank. The brauch pipesare connected to the cylinder and are so valved as to permit liquid totiowonlyin one directionwviz., into the cylinder. The branch pipes 15communicate with a pipe 16, having a detachable flexible extension 17.The extension terminates in a metallic tube 19, having a flared endprovided with a strainer. The pistonrod is driven from the crank-shaftthrough the medium of a pitman, which is made adjustable forautomatically regulating the stroke ot' the piston and the pressure ofthe contents of the tank. To this end the pitman is formed in threesections 21,22, and 23, the former being a tube connected to thepistonrod by a universal joint and having a longitudinal slot. Thesecond section consists of a rod having an angular end 24, protrudingthrough the slot in section 21. A11 adjusting-nut is threaded on theouter end of the section 2l, and a spring 26, encircling the saidsection, abuts the angular end 24 of the section 22 at one end and theadjustingnut 25 at the opposite end, and it Will be IDO readily seenthat the tension of the spring may be varied Within certain bounds. Thesection 23 is slidable on the section 22, and the section 22 isprovidedwith a shoulder 26'. The section 23 is provided with an adjustingnut 27,and thespring 28, which encircles the sections 22 and 23, is confinedbetween the shoulder and the adjusting-nut. The sections 22 and 23 areheld together in any suitable manner, here shown by a lug 23, and whenthere is a maximum pressure in the tank the lug travels in a slot formedin the tube23. The section 23 is .connected to and takes motion from thecrank-shaft, and when the pressure in the tank reaches a predeterminedpoint the springs will yield and the sections of the pitman willtelescope and the stroke of the piston will be diminished or nullitied,as the case may be, and as the pressure is reduced in the tank thelength of stroke will increase.

The construction, operation, and adyantages will, it is thought, beunderstood from the foregoing description, it being noted that changesin the proportions and other details of construction may be resorted towithout departing from the scope of the claims.

Having fully described the invention,what I claim as new, and desire tosecure by Letters Patent, is

l. In a spraying apparatus, a tank adapted to contain liquid underpressure and having a spraying-nozzle in communication with itsinterior, a pump for forcing liquid into the tank, a pitman comprisingsections telescopically connected, springs for holding the sectionsdistended, means for regulating the tension of the springs and meansconnected with the vehicle-wheels for reciprocating the pit-I man.

2. In a spraying apparatus, an air-tight tank; means for drawing liquidtherefrom, a pump for forcing liquid into the tank, a spring-pressedpiston and means for adjusting the tension of the spring, for regulatingthe pressure in the tank.

3. In a spraying apparatus, a tank adapted to hold liquid underpressure, a pump for forcing the liquid into the tank, a pitmancomprising three telescopic connected sections, springs for holding thesections distended, means for adjusting the tension of the springs, acran k-shaft and piston-rod connected by the piston, and means fordriving the crank-shaft.

4. In a spraying apparatus, a tank, a pump for forcing liquid 'into thetank, a fieXible connection in communication with the receptaclecontaining the liquid for conveying it to the pump, a pitman comprisinga central and two end sections, said end sections being slidable on thecentral section, means for holding the section distended, means forregulatin g the resistance of the sectionnretainin g means and suitablegearing for reciprocating the pitman.

5. In a spraying apparatus, atank, apump for forcing liquid into thetank, a pitlnan connected to the piston-rod of the pump, said pitmancomprisinga central section and two tubular sections` slidable thereon,an adjusting-nut on each of the tubular sections, springs encircling thesections and abutting the nuts at one end and fixed projections on thecentral section at the opposite ends and means for reciprocating thepiston.

In testimony whereof I attix luy-signature in the presence of twowitnesses. i
